Hello, We're the Hedge Cutting Staffordshire team, a professional gardener based in Staffordshire. They're versatile, hardy, and add a splash of colour to any garden. In this article, I'll share my insights on the best companion plants for penstemons, particularly suited for our lovely UK climate.
Quick Answer
Penstemons pair well with ornamental grasses, lavender, and salvia. These companions complement their height and colour, thriving in similar conditions.
Understanding Penstemon Needs
Before diving into companion choices, it's essential to understand what penstemons require. They're best planted in well-drained soil and prefer a sunny position, although they can tolerate partial shade.
Why Companion Planting?
Companion planting isn't just about aesthetics; it's also about creating a balanced environment where plants support each other's growth. With penstemons, you'll want companions that don't overshadow them but rather enhance their presence and attract pollinators.
Top Companion Plants for Penstemons
Here are my top recommendations for companion plants that will flourish alongside penstemons:
- Ornamental Grasses: Varieties like Stipa tenuissima add texture and movement, complementing the vertical form of penstemons.
- Lavender: With its contrasting colour and similar growing conditions, lavender adds fragrance and attracts pollinators.
- Salvia: Sharing a similar flowering period, salvias provide a continuous splash of colour and are loved by bees.
Planting Tips
To establish a successful companion planting scheme, timing and placement are key. In the Midlands, it's best to plant in late spring when the soil has warmed up. Ensure each plant has enough space to grow; for penstemons, aim for about 30cm between plants.
| Plant | Preferred Soil | Spacing |
|---|---|---|
| Penstemon | Well-drained | 30cm |
| Lavender | Sandy, well-drained | 30-45cm |
| Ornamental Grasses | Moist, well-drained | 45cm |
Maintaining Your Garden
Once your garden is planted, regular maintenance will ensure it continues to thrive. Water your plants regularly, especially during dry spells, and deadhead your penstemons to encourage more blooms. In Staffordshire, we often face wet winters, so consider mulching to protect roots from frost.
Frequently Asked Questions

Companion planting helps deter pests naturally. Additionally, regular checks and removing affected leaves can help manage pest issues.
When is the best time to prune penstemons?
Prune penstemons in early spring, cutting back old growth to promote new shoots and a healthier plant.
